lN MACHINES FOR TRIMMING THE SOLES AND HEELS OF BOOTS AND SHOIES.,`

Specification forming part of Letters Patent N0. 172.4144, dated January 18, 1876; application filed v OctoberjS, 1875.

` To all whom it mayconceM-L:

Be itlxnown that I,.WILLIAM JACKSON, of London, England, have invented an Improved Machine for Cutting and Shaping the Soles and Heels of Boots and Shoes, of which the following is aspecifcation Myinvention relates to an improved machinefor cutting and` shaping the soles and heels of boots and shoes; and consists in the novel construction and arrangement `of the parts ofthe machine, as hereinafter described. The principal parts of the said machine are as follows, nainely:a rotary cutter. or knife, an adjustable rotating post for supporting the 'boot vor'shoewhile it i-svsubjected tothe action ofthe said cutter, a peculiar device for securing thebo'ot or shoe upon thepos't, and mechanism for rotating'the said post, and for stoppingits rotation'without stopping the rotationv of the. main shaft and thecutter.

Thesaid invention is illustrated in the accompanying' drawings, which l will now proceed to explain.

Figure l is a side elevation ofmy-improved Fig. 2 is a-front elevation of the same. Fig. 3 is a plan or top View, partly in section on-the line m Fig. 1. Fig. 4. shows detached portions ofthe said machine, with a boot-heel beingcut by the same. Fig. illustrates a modification of the said machine.

Like letters indicate the same parts throughout the drawing.

A is a strong fra-me or standard of cast-iron or other suitable material, properly constructed to support the workin g parts of the machine. c is the main or driving shaft, supported to turn freely in suitable bearings 1 l in the said frame. b is the driving-wheel on the outer end of the shaft a., and c is a bevel-tooth wheel on the inner end of the said shaft.

d is a vertical shaft, fitted to turn freely in bearings 2 2 in the frame A. This shaft has on it a bevelpinion, c, which is geared with the vaforesaid bevel-wheel c. At the lower end of this shaft d I iix the cutter f, as clearly shown in Fig. l. Below the said cutter l place the washer g, whose edge projects far enough to workin the seam between the upper and the heel `or sole .of a boot or shoe placed in the said machine,

as clearly shown in Fig. 4. This washer turns loosely or independently of the cutter. The

.guide-plate below it. l I adj ustl the post vertically to any required po- .sition.

said cutter ,and washer are securely held upon the said shaft by a nut, h,or by other suitable t devices which lwill permit the cutter to be readily removed and replaced, so that I may4 olle ofthe 'said guides being' made adjustable laterally by means of screws 7c', or other suitable means, to allow it to be `adjusted to the plate j when required. misa lever for adjustin g or setting the posti nearer to or farther from the cutter' m is a screw )assed through the said lever, with its point resting` on the By means of this screw n is a spring1 tending to keep the said post away from the cutter' when the said lever is released. The disk or block il at the top of the post is preferably rougherred on its upper surface, and it is secured by a screw, 2, or by other means which permit it to be readily removed and replaced. o is a clamping arm or lever, whose fulcrum is at o* in the bracket p, which is fixed or formed on the post z'. The said arm ois provided with an adjusting clam pscrew, o', between which and the block 'il the boot or shoe is held while being operated upon. The outer extremity of the arm o is provided with an eccentric handle, o2, whereby the said arm is readily made fast and released, to allow the boot or shoe to be readily and con,- veniently put upon the post i, secured thereon, and removed when finished. q is a wormwheel fixed on the post 1T, and geared with the worm r, which turns in the bearings 3, fixed on the plate j. The shaft of this worm carries a pulley, s, which is geared by a belt or band with the pulley t on the main shaft a. This pulley t is arranged in combination with4 the sliding disk u, which is provided with pins or studs arranged to enter holes in the pulley t' when the disk u is pressed against the said pulley. This disk is fitted to slide on a feather or key, u', on the shaft a, sothat it will slide eudwise on the said shaft, but is compelled lsaid boot or shoe.

to turn with the same. c is alever Whose fulcruni is at ful, and which has at its. end *U2 a. pin or stud, which projects intothe groove or channel in the periphery of the disk a. By means of this' lever the said disk is moved in-v to, or out of, connection with thev pulley t.

In using my improved machine the boot or shoe is placed on the post i, and secured thereon bythe clampinglever. Then the said post is adjusted by means oi the lever m, and' se cured by the screw m in the proper position for vthe cutter to act on the sole or heel of the The posti having been turned into the proper position to commence cutting, the disk u is moved into connection with thepulley t. The driving-shaft a and cutter heilig continually rotating, motion is communicated by the belt or band to the Worm r, and from this worin vto the Worm- Wheel `whereby the'post i, with the boot or shoe thereon, is rotated. As it rotates the rapidly-revolving cutter f cuts and shapes the surface of the sole or heel, and as the post arrivesat a position opposite to that-inwhich it was first adjusted, the disk u is drawn out of connection vwith the pu-lleyt. then be turned back 'by rotating-the pulley s,

lthe clamp-arm slackened, and 'the Iboolt removedv from Athe said post, and another one placed thereon, the above operations being repeated without stopping the Adri-ving-shaft c. In some i-nstances I so arrange the lever v vthat it is acted on by a projecting arm or rod on the post i or bracket p, or by other sui-table means, to effect the adjustment of the lever c f automatically, so that the machine Wll'be selfacti-ng' Withlregard to this part otitsoperation.

In Fig. 5 I `have illustrated an automatic. device to be used inshapingheels with square l fronts. This device consists of la cam or temlhe post can,

velet, w, fixed 011th@ post i, and a lever, fw,

whosefulcrum isat wz on plate k. The said'lever has an van ti-friction roller,"w3, against which the edge of the cam wworks. This cam, as it rotates with the'post, causes the latter to sol adjust itself to the cutter as to give automatically the l'required shapeto the heel. The said leveris formed with a slot at 104, throughjvhichis passed a screw, fw?, where-- by the `said lever'and'roll'er `caribe secured in .any required position, according to the shape or size of the heel. l

The chiefyadvaintages of my improved machine are as follows, namely: The boot or s hoe is held on the post or support by clamping mechanism instead of by hand, the Work is accomplished with great rapidity,`and the' soles or heels ,of the bofotsf or shoes can be perfectly shaped Without. -theemployment of skilled labor.

I claim as my invention v 1. In combination, lthe pivoted armfo,tlie set-screw7 y0l, and. :the locking-cam o2, for the purpose of clamping a shoegtgo the rotating post, .substantiallyas described.

'2. In combination with the .postathe Worm r, Worm-wheel q, the sliding pla-.tc j, the guides la, lever m, and spring 01;,'su'bstantiallyas -defscri-bed, for :the purpose vof rotating saidpost, and advancing or withdrawing the same from the .cutter without .stoppingthe rotation of the post. f 'i 3. lin combi-nation with vthe post i, the :cam

w, slotted lever wl, 1rollerl w3, Vand screw 105, substantially as described, for thepurpose of automatically vadjusting the postv to 'the cutter.
